@@FuelDropforthewin it would still be very funny if he overengineered his vehicles to look flawless after getting whacked by EMP blasts and having explosions go off behind them
In real life explosives travel at different speeds, you are using tnt so it’s speed of detonation is 7 km/s or 154,340 mph. The speed of detonation dictates the ‘speed’ of the explosion and that means it would have to go at least that speed to get out unscathed. A explosions main destructive force is its shock wave which goes at the close to speed of sound, hence sonic booms, so it would have to be going at the over the speed of sound to remain unscathed if it wasn’t in contact with the explosive. In this case there is conservation of motion so he could have to accelerate to x+154,340 mph (if x is the initial velocity at which the explosion happened), he would need to accelerate to that higher speed more or less instantaneously. If we are going that far then it also matters what the center of ignition is: center, symmetric, or asymmetric. This seems to be an asymmetric explosive because when he got to high enough speed only the left tire was popped. But if we dig even further then you have to consider that the block underneath was not damaged which means it wasn’t the entire side as an ignition point, only the left side on the middle or top. I’m not going through all of those calculations or physics of why that matters but it does have to do with the speed of detonation that we talked about earlier.
@@aidanstapleton5646 in real life explosions go really fast. And they have momentum. So you would need to somehow get another 1200 some M/s of speed the instant after it go boom.
You figured out dynamite is directional, which you can use to your advantage the next time you use it in multi-player! Not a waste of time as a video, and entertaining!
@@Pystrowell, even one block difference may play role in human guided missiles/torpedoes, and since blocks have same position when you drag it from inventory, it is possible to memorize which end is the explosive one
I think it's because trail makers keeps the dynamite in place once triggered but takes a little longer to explode. this means that the reason moving fast protects you is that you move further from the dynamite. when triggering in the front of the vehicle, the dynamite doesn't clear the vehicle but ruther explodes in the middle of the vehicle.
In theory, it makes sense. In Trailmakers logic, this is impossible. He's traveling at a certain speed and the explosion damage is happening behind him on the engines. Power core explosions are the same as dynamite explosions, so they'd be subject to the same time-space delay and effect things a bit behind them. If it were the engines exploding, then the engines immediately behind Scrapman would also explode, meaning his seat (also a power core part) would also be subject to explode. Like I'm not doubting your opinion at all. It's just by the very nature of this experiment, that shouldn't matter at all because all of that damage should be happening behind the point of detonation relative to the point of detonation. So if an engine explodes and is capable of taking out the engine immediately next to it while moving at that speed, then it voids the entire experiment because then there would be no speed in which damage could be "out ran." I don't have a satisfactory alternate explanation for it, just the counter point of whatever dynamite explosion damage is subject to, all other explosion damage is subject to.
I do not think there is a propagation speed of the explosion. I think explosions are instant in their spread. What Scrapman observing is a result of the delay between triggering of the dynamite and explosions occurrence.

Scrapman: let’s design a vehicle that can go faster than explosions Also Scrapman: *accidently makes a supersonic car* The supersonic regime will never leave you
So, out of curiosity, I wanted to see if I could calculate the dynamite block's explosion speed I set up one block of dynamite at the end of a line of 20 accumulator blocks (vertically aligned) with each accumulator pointed at their own number display a safe distance away. An XOR gate toggle triggers all of the accumulators and the dynamite at the same time, meaning any accumulators that get destroyed will stop counting and yield a measurable result The dynamite block consistently destroys 11 of the accumulators, all of which stop at a value of 0.03 (accumulator settings: range 0 to 100, scale of 1.00). Note: there is no 'gradient' to the shockwave/explosion radius, the whole area is affected at the same time. Anyway, 4 single block spaces = 1 meter, meaning the explosion travels 2.75 meters in 0.03 seconds, which translates to about 91.67 m/s
Interesting. That implies that Scrapman having to move at 600kmph is just to distance himself from the blast radius. If he set the explosive off 11 blocks behind himself then he should see no damage around 300kmph.
This could be useful if the Devs ever combine the Dynamite + 1x2 & 2x2 Cone Blocks together with the explosive part of the Code in the front Cone Tip to create... the "Warhead" Block! :D Aerodynamic Boom Tip for our Player Created Missiles/Torpedoes/Rockets? Yes please! :D
That wouldn't matter in this one case because the point of explosion ends up tracking ahead of the point of damage (theoretically). If this is the case, which Scrapman is testing, then the engines, which are power core blocks, would be subject to the same weird physics as dynamite, another power core block. But there's a weird damage pattern when he has it tacked on near the front of his vehicle. I think he should have tested with an explosive extended out in front of him as well. There's clearly a level of omni directional damage going on that is probably throwing all the variability in there. In otherwords, while the TNT is on top of his creation he's experiencing damage downward he never observed before with the TNT hanging off the back just a little bit off the ground and nothing under it. I can't say for sure, but I would say that would explain it a little more. If it was a case of other power cores exploding, then all of his engines and his seat would have exploded.
Lol ScrapMan was testing ramping up speeds by intervals, 600, 700, 800. And then he casually picks the speed of sound, like "Supersonic is roughly 12-like-37 or so" and its the exact number! later on perfectly timing the 2 explosions 23:43
If you put a 1x1x2 block next to the tnt it seems to blow up at 601. When you switched the last motor to the 1x1x2s you didn't put one above the tnt so you never had a block at the same position as the wheel. Also if you ever want to look at this again, to tnt with only one triggered by the speed sensor seems to be able to blow some motors up. Love your videos.
If 2 Block ~ 1 m, the explosion reaches the ~ 7 m explosion radius in ~ 1/30 s, which i assume is the physics tickrate. So to survive a frontal hit the entire vehicle needs to clear the explosion radius in 1/30 s. For the car in the video, it would be >mach 2
The segmentation thing made me have an idea: race or something with segmented vehicles. It would be like a bug or somthing with a max amount of segments. Each segment can have only have one type of use, like engine, wheels, weapon, etc. this could be done with any vehicles
In reality, shockwaves still consists of particles. As such, conservation of momentum applies as usual - but only for the first particles. The particles that are hit by those first particles don't have any momentum, but are pushed on by particles that have both the momentum from the vehicle AND the explosion, hence they would act as a bigger explosion towards the front and a smaller explosion towards the back.
4:28 Today i learned that vehicle damage is dependent on your vehicle’s axis to the world When he’s slanted on the grid he takes out 2 black engines, when he’s straight on he takes out 1 black engine
It could also be that explosions are grid based, so being misaligned made the vehicle intersect more of the explosion. It should be possible to test this by putting an explosive in the middle of a bunch of small blocks and seeing if different blocks get destroyed based on orientation
You should do a PT.2 of this, but see how fast you need to go with the TNT further into the vehicle to see if the speed needed to outrun the TNT is linier or exponential per block
OH boy! You can go so much further with this, try 2 dynamites, try a cannon pointing to the body and shoting it, going to the space map and see if speeds on the scale of 2k+ kh affect it, Does it matter if you are underwater or not or even if atmosphere matters? Looking forward to those experiments!
Another experiment idea: Build the smallest, hollow but enclosed shape around a block of TNT that does not take any damage. Would be neat to know the safe distance from an explosive, as well as the shape of that dangerous volume.
Gonna first point out the idea you used for testing was great, but, i feel a couple of extra thoughts would have made it better. Firstly, to pin down the explosive radius of the dynamite relative to the vehicle without movement. The other idea was to try and place the dynamite at the front, since the vehicle design was only capable of reacting with the radius of the explosion, but, you could have had a lot more testing and fun if you were able to test against the diameter and also use the entire length of the vehicle, to try and push it farther. To escape the explosion when you have it at the front requires a lot more movement. It appears that the explosion can only be escaped because the activation of it is done a frame after the trigger, suggesting that the trigger of the dynamite drops an explosion object into the game world, which then requires a frame to be initiated using the usual game update loops. As you mentioned the conservation of momentum - you are 100% correct. If the momentum were conserved, you would never outrun the explosion unless you could accelerate to the escape speed in one single frame.
Another thought is about how the escape works. To clear the explosion the rear of the vehicle needs to move more than the explosive radius in one frame, you could experiment with differently shaped vehicles, what about a vehicle with a circular hollow/cutout at the rear?
It could also be possible they attempted to replicate the real behaviour of explosions, which expand from a centre point over a very short period of time, so, the explosion is only tiny on the first frame it triggers.
I think you should try to build a vehicle completely immune to explosions, because it would require a trade-off between speed and length, which would be really interesting.
I wouldn't be surprised if the screen cracks are because the dynamite is exploding, which makes you lose a block (the dynamite), which the game registers as damage.
Hi scrapman. Day 27 of asking you to make a gyro free stol plane (short takeoff and landing) or a bush plane and try to get the shortest takeoff and landing you can (in trailmakers)
The way I see it is that shooting a bullet perpendicular would make the wind put pressure on the bullet pushing it to the side missing the target since the target would essentially be driving as well
Suggestion (Day 1): “Swimming tanks” So basically you’re gonna use a preset tank and make it swim, no aim assist, no changing the tank itself, instead you will need to make a vehicle to carry the tank like a landing craft with the ability to let the tank go, it will be an armed race around an island and once you reach the finish line you will let the tank go and whichever tank reaches land first wins. No energy shields of course unless you use multiple blasters
Dynamite explosions DEFINETLY vary with your ange and only with that. Every single time you changed the angle you drove at is when the damage you took changed, otherwise it stayed the exact same down to how damaged blocks got. At around 15:40 it was also the angle, which changed based on when you started accelerating after respawning (as you can see from the skidmarks). My guess for why this happens is because dynamite doesn't spawn a sphere and maybe something more like hitscan as the explosion damage radius, or spawns a sphere at a speed with the equivalent of 600 kph travel speed. Don't ask why I attempt to decipher Trailmakers code from what the game does, (this is not my first time doing this) I don't know either. My guess to the wierd stuff at around 22:00 is that the explosion is dealing its damage from a stationary location and you are moving out from under it during that, making the explosion damage travel down your vehicle unless it snaps the vehicle in parts as that causes you to slow down a lot.
Without considering what was shown, I would just guess the speed of sound or not possible. In reality, the speed of sound typically limits the explosion propagation. So if you are going faster than it it can't catch up. Technically though if you go fast enough you reduce the impact of the explosion to reduce the damage even below the speed of sound. What I think would be an interesting test is to try to map out the explosion in 3D (or at least 2D where one is the direction of travel) to see if it is a sphere at the point of the explosion but delayed, making it appear as a sphere on the moving creation which is displaced from the explosive; or if it actually propagates outwards creating a different shape in the moving creation.
Hey scap! I dont know if you know this but you can make the center of mass under the creation by putting more weight under it with small conections that dont intefear with the center of mass (basicly a hole where the center of mass is)! When doing that you could make your creatuon basicly invinceble sence your wepons aim to the center of mass! Would make a good/intresting video
You should try to create a machine that can spin and launch a litrle missle really high or far like the company "Spin Launch" for the creating real life machines you used to do
I think the explosion travels at 600hm/h. As for the later testing with the explosion at the front, the explosion is in all directions. This means part of the explosion is traveling 600km/h backwards and the back of your creation is traveling at whatever speed into it.
You should've tested it at like 1300kph with the dynamite at the back to test if the screen-shake happens when it certainly didn't cause damage. You also could've tried using a rocket aimed downward to cause an explosion to make sure it behaves like a dynamite. This would have been easier to test in space with boosters up to much higher speeds.
As I understand it, a shockwave is a wall of compressed medium (air in this case). If that is the case, then explosions of any size and power can only travel at the speed of sound max (specifically the shockwave). The ait can't vibrate other air fast enough to push the shockwave supersonic, that's like trying to race air against itself. As for the game, an explosive at the back of your vehicle will explode in a sphere (maybe??), only half of which will ever touch the vehicle. Maybe that somehow correlates to half the speed of sound you are reaching?
with the tires the explosion is seat dependent. The closer to the seat that the explosion is dependent on how it interacts with your creation. Like with the aiming of most weapons.
My prediction was correct on "where the explosive super sonic damage would happen." That is, I predicted Scrapman would hit a wall before going supersonic because it had to happen. IT ALWAYS HAPPENS when pursing ground supersonic speeds is a thing. It is an inevitability, so I placed my bets on he was going to explode on the wall before ever breaking the sound barrier and I was technically correct.
day 7 of Suggesting 2v2 or free for all "realistic" tank battle. By realistic, i mean the only allowed camera angles would be first person and via camera blocks (to represent vision ports and whatnot on a tank), and tank steering would be required. the rest of it would be up to the builder (turreted or casemate, etc)
Spleef, but random switching timers? The car switch 180 degrees, but at totaly random times. Just use the same cars as you did 5 month ago, but randomize timers!
20:24 Since the explosion did the most damage in roughly half of the vehicle's length, I expect the full immunity speed to be >2x as fast. I'll see if I'm right when I finish the video. 22:55 Edit 1: wait I forgot that the dynamite will start immediately decelerating, so depending on the drag it may be way more than that xD Edit 2: just finished the video and it seems accurate. I think the reason the explosion damage seems delayed is simply because it takes a moment to reach a sufficient radius to damage the engines (this may depend on where exactly their hitboxes are). I thought it could be just that the explosion is slightly delayed, but I feel like this doesn't explain how the engine right under the dynamite's attachment point also gets damaged (unless the kinetic energy of the moving dynamite is sufficient, I suppose - but then I'd expect it to bounce way up which I don't think it's doing, though I'm not sure. If it does, it could be yet another explanation of what's going on). Also I suppose the speed at which you'd get full immunity would be the speed at which the explosive would travel from the point of attachment/triggering past the end of your vehicle within one tick. Which is variable and also probably a _really_ large number, considering the aforementioned drag.
I wonder what would happen if the speed was locked at the speed of the explosion instead of still accelerating. Would be a fun idea to revisit this with the condition of the vehicle speed locks at the speed you explode the dynamite
Idk if this is in the game but I think you should have used a speed limiter because even though there is a speed sensor you continue to gain speed and there could be a slight delay. You could also be gaining speed and speeding away from the explosion.
The explosion damages your construction every time, because the exploding dynamite is part of the construction. So the screen shaking and cracking should be triggered every time.
What if the explosion speed is based on the number of frames per second? Say an explosion happens at some given point in the 60 frames in a second, maybe moving at 10 times the speed would get you through enough frames and far enough away to avoid the explosion. So say you play at 30 fps maybe you only need to go 300 instead of 600. Just an idea and i dont have trailmakers to test it.
Somebody "me included" needs to make a graph of damage and speed, Because it doesn't seem to be linear. Also try adding more smaller blocks/elements for more precision Maybe even try to create (predict) a function?
The last experiment you're measuring the propagation speed. I wonder if the explosion propagation preserves any momentum from speeding vehicle but if so, you could just deduct the 600 base speed and based on your observation estimate the propagation to be around 1 block per 100km/s.
Don't guns and stuff generally target the center of the creation? So if you dogfight with rockets (assuming they have the same damage calcs as dynamite) if you use a more compact creation that can go over 700 it can maybe avoid damage even if hit. Don't know how realistic that would be but it is interesting. Also now knowing about how dynamite explode could be interesting in fights like explosive catapults etc to get a better radius of damage
Maybe it's framerate dependant? If you have vsync your frame rate might be capped to 60fps 60fps = 600km/h Would explain why it was inconsistent at 600km/h
Multi-player submarine homing torpedo battle. If not using the new logic perhaps a team competition with a torpedo, on offense, and a submarine on defense the team whose submarine survives longest wins.
I did some math, I'm probably wrong, but it was fairly accurate for the tests you did, but my math says it'll take around mach 2 to not take any damage from the explosion
My guess is that there isn’t any ‘explosion speed’ but like all games, there is a number of ticks every second and because you’re going so fast, the game camt keep up
I have a feeling that to get full immunity for your vehicle, you'd have to go 1800km/h or 2100km/h or thereabouts. (Based on how far back the damage moved between going 1000km/h and 600km/h.)
I tested it with this vehicle, and with the explosive at the front, you need to be going more than 1500 kph. At 1500 kph it destroys everything after the first white section. It's weird how at 1234 kph it destroys everything after the middle of the second black section, and at 1500 kph, the explosion is "faster".
also the acceleration isn't stopping at the time it explodes, so your measurement of 601 isn't quite accurate, since as the explosion takes the time to appear, you are already faster than 601.
Objects in motion stay in motion. You can't outspeed an explosion if the source is moving at the same speed as the that which is running. As the speed of the explosion itself is about 195x the speed of sound and no vehicle is capable of that speed, at least IRL lol. In the game, who knows.
So we know that the explosion starts on that one side of the dynamite. But then why at like 800+ KPH does it also damage the other side? I think that at the moment the explosive is triggered it is then nailed in place at the exact spot it’s triggered at. Then that one side starts the explosion. That’s what he tested at 601. So then the explosion could move to the other side and that’s why at 800+ the damage switched sides? That’s just my guess anyhow.
I guess you should‘ve set the vehicle on a speed limit, because by the time the dynamite explodes you‘ve already gained some more speed since you‘re constantly accelerating… so my guess is, that this is why your test is inconsistent.
For some reason every scrapman multiplayer event from that day onwards that involved strapping TNT to the vehicle and dodging EMPs had his vehicle able to go over 600kmph.
They give the point/win based on whether the TNT goes off at all, not necessarily whether it disables the vehicle

It appears that the explosion can only be escaped because the activation of it is done a frame after the trigger, suggesting that the trigger of the dynamite drops an explosion object into the game world, which then requires a frame to be initiated using the usual game update loops. As you mentioned the conservation of momentum - you are 100% correct. If the momentum were conserved, you would never outrun the explosion unless you could accelerate to the escape speed in one single frame.
Another thought is about how the escape works. To clear the explosion the rear of the vehicle needs to move more than the explosive radius in one frame, you could experiment with differently shaped vehicles, what about a vehicle with a circular hollow/cutout at the rear?
It could also be possible they attempted to replicate the real behaviour of explosions, which expand from a centre point over a very short period of time, so, the explosion is only tiny on the first frame it triggers.
Scrap man ur the best RUclipsr ever i would like if you showed how people make mech legs and stuff like that
I think you should try to build a vehicle completely immune to explosions, because it would require a trade-off between speed and length, which would be really interesting.
I wouldn't be surprised if the screen cracks are because the dynamite is exploding, which makes you lose a block (the dynamite), which the game registers as damage.
2:39 "A wipeout like that, and I hardly got dinged. Man, these cars can really take punishment!
You flame hair is a good visual representation of the what's happening with the explosions
I just now realized that scrapman has actual nerds that talk like they are 1000 years from the future
Hi scrapman. Day 27 of asking you to make a gyro free stol plane (short takeoff and landing) or a bush plane and try to get the shortest takeoff and landing you can (in trailmakers)
The way I see it is that shooting a bullet perpendicular would make the wind put pressure on the bullet pushing it to the side missing the target since the target would essentially be driving as well
Idea :
Battlebots.....
ON WATER!!!!!!!!!!!!!!!!
Suggestion (Day 1): “Swimming tanks” So basically you’re gonna use a preset tank and make it swim, no aim assist, no changing the tank itself, instead you will need to make a vehicle to carry the tank like a landing craft with the ability to let the tank go, it will be an armed race around an island and once you reach the finish line you will let the tank go and whichever tank reaches land first wins. No energy shields of course unless you use multiple blasters
Maybe a tiny land section too although I’m not sure about that one
Dynamite explosions DEFINETLY vary with your ange and only with that.
Every single time you changed the angle you drove at is when the damage you took changed, otherwise it stayed the exact same down to how damaged blocks got.
At around 15:40 it was also the angle, which changed based on when you started accelerating after respawning (as you can see from the skidmarks).
My guess for why this happens is because dynamite doesn't spawn a sphere and maybe something more like hitscan as the explosion damage radius, or spawns a sphere at a speed with the equivalent of 600 kph travel speed.
Don't ask why I attempt to decipher Trailmakers code from what the game does, (this is not my first time doing this) I don't know either.
My guess to the wierd stuff at around 22:00 is that the explosion is dealing its damage from a stationary location and you are moving out from under it during that, making the explosion damage travel down your vehicle unless it snaps the vehicle in parts as that causes you to slow down a lot.
he's done so much of everything that he's picking apart the game to the bone
scrapman everytime he makes a video testing something: "who are you?🤨 why are you watching this? 🤨👀 what's so entertaining about this? 🤨👀🤔"
Without considering what was shown, I would just guess the speed of sound or not possible.
In reality, the speed of sound typically limits the explosion propagation. So if you are going faster than it it can't catch up.
Technically though if you go fast enough you reduce the impact of the explosion to reduce the damage even below the speed of sound.
What I think would be an interesting test is to try to map out the explosion in 3D (or at least 2D where one is the direction of travel) to see if it is a sphere at the point of the explosion but delayed, making it appear as a sphere on the moving creation which is displaced from the explosive; or if it actually propagates outwards creating a different shape in the moving creation.
Hey scap!
I dont know if you know this but you can make the center of mass under the creation by putting more weight under it with small conections that dont intefear with the center of mass (basicly a hole where the center of mass is)!
When doing that you could make your creatuon basicly invinceble sence your wepons aim to the center of mass!
Would make a good/intresting video
You should try to create a machine that can spin and launch a litrle missle really high or far like the company "Spin Launch" for the creating real life machines you used to do
Just to see how high or far Trailmakers physics let you go
Look for "I converted the SpinLaunch into an Instrument of Destruction!"
ScrapMan has already explored this content with the SpinLaunch before
@@tylerphuoc2653 yeah but Tailmakers would be sick because you can sit on the rocket and launch the seat😂
18:35 could be because of the fact that blocks like engine explode when damaged so it just caused a chain reaction
DAY 2 OF ASKING You should try to make a supersonic vehicle in trailmakers but it has terrible aerodynamics
I think the explosion travels at 600hm/h.
As for the later testing with the explosion at the front, the explosion is in all directions. This means part of the explosion is traveling 600km/h backwards and the back of your creation is traveling at whatever speed into it.
You should've tested it at like 1300kph with the dynamite at the back to test if the screen-shake happens when it certainly didn't cause damage. You also could've tried using a rocket aimed downward to cause an explosion to make sure it behaves like a dynamite.
This would have been easier to test in space with boosters up to much higher speeds.
Maybe the 2x1 explosive has two 1x1 charges that detonate in sequence... ? That could explain the damage being asymmetrical.
As I understand it, a shockwave is a wall of compressed medium (air in this case). If that is the case, then explosions of any size and power can only travel at the speed of sound max (specifically the shockwave). The ait can't vibrate other air fast enough to push the shockwave supersonic, that's like trying to race air against itself.
As for the game, an explosive at the back of your vehicle will explode in a sphere (maybe??), only half of which will ever touch the vehicle. Maybe that somehow correlates to half the speed of sound you are reaching?
with the tires the explosion is seat dependent. The closer to the seat that the explosion is dependent on how it interacts with your creation. Like with the aiming of most weapons.
I would love to see you try to make flares for a plane
My prediction was correct on "where the explosive super sonic damage would happen." That is, I predicted Scrapman would hit a wall before going supersonic because it had to happen. IT ALWAYS HAPPENS when pursing ground supersonic speeds is a thing. It is an inevitability, so I placed my bets on he was going to explode on the wall before ever breaking the sound barrier and I was technically correct.
When the new update comes out, you guys should build an amphibious vehicle to battle.
its the Doppler effect but with explosives instead of sound
This collab was perfect!
"*collab*"
Multiplayer monday idea, Catapult Olympics in trailmakers using the barrels on the danger-zone map as the launch item
day 7 of Suggesting 2v2 or free for all "realistic" tank battle. By realistic, i mean the only allowed camera angles would be first person and via camera blocks (to represent vision ports and whatnot on a tank), and tank steering would be required. the rest of it would be up to the builder (turreted or casemate, etc)
Spleef, but random switching timers?
The car switch 180 degrees, but at totaly random times.
Just use the same cars as you did 5 month ago, but randomize timers!
20:24 Since the explosion did the most damage in roughly half of the vehicle's length, I expect the full immunity speed to be >2x as fast. I'll see if I'm right when I finish the video.
22:55 Edit 1: wait I forgot that the dynamite will start immediately decelerating, so depending on the drag it may be way more than that xD
Edit 2: just finished the video and it seems accurate. I think the reason the explosion damage seems delayed is simply because it takes a moment to reach a sufficient radius to damage the engines (this may depend on where exactly their hitboxes are). I thought it could be just that the explosion is slightly delayed, but I feel like this doesn't explain how the engine right under the dynamite's attachment point also gets damaged (unless the kinetic energy of the moving dynamite is sufficient, I suppose - but then I'd expect it to bounce way up which I don't think it's doing, though I'm not sure. If it does, it could be yet another explanation of what's going on).
Also I suppose the speed at which you'd get full immunity would be the speed at which the explosive would travel from the point of attachment/triggering past the end of your vehicle within one tick. Which is variable and also probably a _really_ large number, considering the aforementioned drag.
the engines exploding because they are power blocks are probably throwing some of these tests off
I wonder what would happen if the speed was locked at the speed of the explosion instead of still accelerating. Would be a fun idea to revisit this with the condition of the vehicle speed locks at the speed you explode the dynamite
Lol I saw the video 3 minutes past the release but I had no internet to play it. Now 3 hours later I'm here😂
Um noticed it left 1 more engine Everytime you were diagonally moving the DMG might actually matter which direction your moving
Idk if this is in the game but I think you should have used a speed limiter because even though there is a speed sensor you continue to gain speed and there could be a slight delay. You could also be gaining speed and speeding away from the explosion.
Always on point
The explosion damages your construction every time, because the exploding dynamite is part of the construction. So the screen shaking and cracking should be triggered every time.
What if the explosion speed is based on the number of frames per second? Say an explosion happens at some given point in the 60 frames in a second, maybe moving at 10 times the speed would get you through enough frames and far enough away to avoid the explosion. So say you play at 30 fps maybe you only need to go 300 instead of 600. Just an idea and i dont have trailmakers to test it.
If you need more distance in the test map, Go from Corner to opposite corner. You'll have more space. Think of it like measuring a TV
he already does that
Somebody "me included" needs to make a graph of damage and speed, Because it doesn't seem to be linear.
Also try adding more smaller blocks/elements for more precision
Maybe even try to create (predict) a function?
The last experiment you're measuring the propagation speed. I wonder if the explosion propagation preserves any momentum from speeding vehicle but if so, you could just deduct the 600 base speed and based on your observation estimate the propagation to be around 1 block per 100km/s.
This very much reminds me of the time I had a missile that was so fast it could outrun its own detonation
ok please try this, stack dynamite off the back like a tail and program it to go off in a chain, a vehicle with an explosion trail
Don't guns and stuff generally target the center of the creation? So if you dogfight with rockets (assuming they have the same damage calcs as dynamite) if you use a more compact creation that can go over 700 it can maybe avoid damage even if hit. Don't know how realistic that would be but it is interesting. Also now knowing about how dynamite explode could be interesting in fights like explosive catapults etc to get a better radius of damage
22:25 because i love watching ScrapMan videos
Maybe it's framerate dependant?
If you have vsync your frame rate might be capped to 60fps
60fps = 600km/h
Would explain why it was inconsistent at 600km/h
Multi-player submarine homing torpedo battle. If not using the new logic perhaps a team competition with a torpedo, on offense, and a submarine on defense the team whose submarine survives longest wins.
day 1 of asking scrap man to have a fight but you can only use custom weapons
ScrapMan testing the limits of DELAYED ANNIALATION...
Maybe sometime to do with you still accelerating as the explosion goes off
I did some math, I'm probably wrong, but it was fairly accurate for the tests you did, but my math says it'll take around mach 2 to not take any damage from the explosion
The minimum speed you need to run so that your farts cannot catch up with you
My guess is that there isn’t any ‘explosion speed’ but like all games, there is a number of ticks every second and because you’re going so fast, the game camt keep up
I STILL REQUEST THE MAKING OF SUPERCAR WITH HOVER PADS RACING THEM THROUGH SOME OF THE RACES
Hey, do you think you can make tutorial on how to make bipedal mech legs even if it’s just the logic.
I have a feeling that to get full immunity for your vehicle, you'd have to go 1800km/h or 2100km/h or thereabouts. (Based on how far back the damage moved between going 1000km/h and 600km/h.)
How does this guy, this S Tier RUclipsr, not even have 1M subs???????? I just assumed he had like 10M subs.
Fr
I tested it with this vehicle, and with the explosive at the front, you need to be going more than 1500 kph.
At 1500 kph it destroys everything after the first white section.
It's weird how at 1234 kph it destroys everything after the middle of the second black section, and at 1500 kph, the explosion is "faster".
Day 22 of asking Scrapman to battle with mechs
also the acceleration isn't stopping at the time it explodes, so your measurement of 601 isn't quite accurate, since as the explosion takes the time to appear, you are already faster than 601.
Scrapman with yellow shirt
Once in a blue moon occurance
He weared it before
Ehh not really
@@Pale_Kingg rarely
Doing the devs work for them here haha
You could use propellers with drag glitch to go super fast and completely avoid the explosion.
hasn't he already made it clear he doesn't use glitches?
Chinook/gunner fight when???
Objects in motion stay in motion. You can't outspeed an explosion if the source is moving at the same speed as the that which is running. As the speed of the explosion itself is about 195x the speed of sound and no vehicle is capable of that speed, at least IRL lol. In the game, who knows.
maybe it is because it has blocks it makes contact with opposed to hitting the ground
So we know that the explosion starts on that one side of the dynamite. But then why at like 800+ KPH does it also damage the other side?
I think that at the moment the explosive is triggered it is then nailed in place at the exact spot it’s triggered at. Then that one side starts the explosion. That’s what he tested at 601. So then the explosion could move to the other side and that’s why at 800+ the damage switched sides? That’s just my guess anyhow.
I guess you should‘ve set the vehicle on a speed limit, because by the time the dynamite explodes you‘ve already gained some more speed since you‘re constantly accelerating… so my guess is, that this is why your test is inconsistent.
